Those photos are synced from computer maybe with iTunes or some third-party apps, you can't delete them directly on iPhone. iTunes helps :

Step 1. Open iTunes and connect with your iDevice. Click the Device button.

Step 2. Under photos > choose Sync Photos > Choose "Copy photo from Photos" > Below check "Selected Albums" but DO NOT select any albums > Make sure there is 0 photos you choose > Apply.
